Help tame body motion and sharpen steering response on your truck with the KYB Gas-a-just Suspension Strut (MPN 5510049), a high-pressure monotube gas strut that drops in as a front-position replacement for the 2021-2025 Ford F-150 (see the Buyer's Guide tab for engine-level fitment).

Built as an OE monotube replacement, the Gas-a-just uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen chamber with a floating piston that supports a comfortable ride during normal driving and adds performance on demand. It's designed to help restore the original control and handling of the 2021-2025 Ford F-150.

  • Monotube design: separates the gas and oil for fade-free operation and instant response.
  • Higher gas pressure: responds quickly to help improve steering response.
  • Triple chrome-plated piston rod: an ultra-smooth rod that reduces seal wear; fluid leaking can be a cause of strut failure.
  • Electronic safety support: helps keep electronic safety systems performing as the vehicle manufacturer intended, since they depend on the suspension, brakes and tires.

Sold individually; replacing both front struts together is recommended for balanced handling.

Frequently Asked Questions

What vehicle does this KYB strut fit?

It is a front-position replacement for the 2021-2025 Ford F-150. Check the Buyer's Guide tab to confirm the exact engine and configuration for your truck.

What is a monotube gas strut?

A monotube design uses a single tube with the gas and oil separated by a floating piston, which helps deliver fade-free operation and instant response.

Why does the KYB Gas-a-just use high-pressure nitrogen?

The high-pressure nitrogen chamber with a floating piston supports a comfortable ride during normal driving and provides added performance on demand, while the higher pressure helps improve steering response.

Do I need to replace both front struts at once?

Each strut is sold individually. Replacing both front struts as a pair is recommended for balanced, even handling.

What are signs a strut may need replacing?

Common signs include excessive body motion, reduced handling and control, or fluid leaking, which can be a cause of strut failure. Diagnose the cause before replacing.
